When surveying the computer technology available for working out mathematical problems, one fact quickly becomes apparent-most personal and super- computers are not designed for computation. Without the aid of costly and often only partially compatible software programs, most computer operating systems cannot perform mathematical computations. Mathematics textbooks and handbooks provide useful equations, but they do not offer accessible means for evaluation. The HP48SX, an object-oriented computer containing a custom CPU and operating system, is designed specifically for this task. With a low-cost computer chip and an inexpensive calculator, the HP 48SX Engineering Mathematics Library: An Introduction to Symbolic and Complex Computation with Applications package offers users an affordable and versatile alternative for solving simple and complex problems.
